Mr. Bidgway fairly questioned, in the August number of the same periodical, p. 493, 

 whether the species was not the Rough-wing, which breeds exactly as Dr. Haymond 

 described, and as the two species are so similar as to be confounded sometimes, even by 

 good observers. Dr. Haymond shortly sent me a second communication to the same 

 effect, which I published in the ' Bulletin ' of the Nuttall Club, vol. i. n. 4, Nov. 1876, 

 p. 96. In this other instance, < a weather-board bad become detached from the building,' 

 leaving a small opening, in which I watched for two days a Bank-Swallow building "a 

 nest.' Since then, however, he informed me by letter, in answer to my further inquiries, 

 that Mr. Bidgway was right in supposing that the birds were really Bough-wings, and 

 not Bank-Swallows." 



The birds described and figured in the accompanying Plates are in the British 

 Museum. An adult and a young bird are represented.
